Answer:
subtract 3 from both sides.
Solve the first for y
y=13x-90 and the second is y=x^2-x-42
When there is/are solutions y=y so we can say:
x^2-x-42=13x-90 subtract 13x from both sides
x^2-14x-42=-90 add 90 to both sides
x^2-14x+48=0 expand so that it is easy to factor...
x^2-6x-8x+48=0 now factor 1st and 2nd pair of terms
x(x-6)-8(x-6)=0
(x-8)(x-6)=0
So there are two solutions, when x=6 and 8.
Using either original equation we can find the corresponding values for y. I'll use y=13x-90 because it is easier...
y(6)=-12, y(8)=14 so the two solutions are the points:
(6,-12) and (8,14)
Answer:
F = (G * m2)
Step-by-step explanation:
1: The first main step is to divide so g*m1sqm = F/d
Then just divide in m1m2 from both sides then you will get the answer
Hope that helps.

The answer is the 3rd choice.
Notice how every 'x' unit it goes up 3 'y' units
